Plasticized poly (vinyl chloride) (PVC) gel is a promising electroactive polymer material for soft actuators and sensors, and it has attracted extensive attention and interest in multi-disciplinary fields. Chlorinated polyvinyl chloride (CPVC) has enhanced mechanical and chemical properties and shows a promising potential for fabricating gel materials for electroactive polymer gel actuators. Thus, we proposed a novel soft actuator based on CPVC gels. We studied the properties of CPVC gels with various technologies, such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM) analysis, thermogravimetric analysis (TGA), Furthermore, CPVC gel actuators were fabricated and the influence of membrane thickness and plasticizer content on the basic characteristics was investigated. The experimental results show that the CPVC gel actuator with a higher content of DBA has a better strain than that of the actuator with lower amount of DBA despite the membrane thickness. With the same ratio of DBA, the CPVC gel actuator has a better performance than the traditional PVC gel actuator under a low applied load. The maximum strain and stress of the CPVC gel (CPVC : DBA = 1 : 2.5) actuator are 9% and 0.12 MPa respectively at 400 V, which reaches the same level of the PVC gel actuator with higher content of DBA (PVC : DBA = 1 : 4). These results demonstrate a good potential of the proposed CPVC gel soft actuator for practical application.
增塑聚氯乙烯（PVC）凝胶是一种用于软致动器和传感器的很有前景的电活性聚合物材料，它在多学科领域引起了广泛关注和兴趣。氯化聚氯乙烯（CPVC）具有增强的机械和化学性能，在制造用于电活性聚合物凝胶致动器的凝胶材料方面显示出有前景的潜力。因此，我们提出了一种基于CPVC凝胶的新型软致动器。我们用各种技术研究了CPVC凝胶的性能，如傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）分析、热重分析（TGA）。此外，制备了CPVC凝胶致动器，并研究了膜厚度和增塑剂含量对其基本特性的影响。实验结果表明，尽管膜厚度不同，但二丁胺（DBA）含量较高的CPVC凝胶致动器比DBA含量较低的致动器具有更好的应变。在相同的DBA比例下，在低施加负载下，CPVC凝胶致动器比传统PVC凝胶致动器具有更好的性能。CPVC凝胶（CPVC∶DBA = 1∶2.5）致动器在400 V时的最大应变和应力分别为9%和0.12 MPa，达到了DBA含量较高（PVC∶DBA = 1∶4）的PVC凝胶致动器的相同水平。这些结果表明所提出的CPVC凝胶软致动器在实际应用中具有良好的潜力。
